Assessment of Arabic Web-Based Knowledge About Root Canal Treatment: An Infodemiologic Study.

BACKGROUND: Root canal treatment (RCT) is a vital dental procedure aimed at preserving tooth function and minimizing infection. Access to accurate and comprehensive information about RCT is crucial for informed decision-making. With the increasing reliance on the Internet for health-related information, it is essential to evaluate the quality and readability of web-based RCT content, particularly in Arabic-speaking regions. METHODS: This study conducted an extensive web search using three major search engines (Google, Yahoo, and Bing) to identify Arabic-language websites providing information on RCT. Inclusion criteria required websites in Arabic with comprehensive RCT content. Quality assessment employed the DISCERN instrument, JAMA benchmarks, and Health on the Net (HON) assessment tools, while readability was assessed using Flesch Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), and Flesch Reading Ease (FRE) metrics. RESULTS: Out of 152 websites included, the majority were affiliated with university/medical centers (56.58%) and non-profit organizations (28.29%). Quality assessment revealed that the mean DISCERN score was 2.82, indicating moderate quality. Only one website achieved a high DISCERN score. JAMA benchmarks showed limited compliance, with only two websites meeting all criteria. The HON code was found on only five websites. Readability analysis indicated that most websites were reasonably easy to read by the general population. CONCLUSION: This study highlights the significant gap in the quality and reliability of web-based health information related to RCT in Arabic. While the majority of websites examined in this study did not meet established quality standards, there is a clear need for improvements in the accuracy and comprehensiveness of online resources. Patients seeking information on RCT should exercise caution and consider consulting healthcare professionals for trustworthy guidance. Further research should explore strategies to enhance the quality of web-based health information and expand the scope of evaluation to ensure that individuals have access to reliable resources for making informed decisions about their dental health.

Results of Modified Stenströms Technique Otoplasty and Patients' Satisfaction at King Fahad Armed Forces Hospital (KFAFH).

Background Globally, the prevalence of protruding ears is relatively frequent. Ear deformities manifest due to underdevelopment of the antihelical fold, conchal hypertrophy, and/or an obtuse conchoscaphal angle. The availability of multiple approaches proves that there isn't a single optimal accepted procedure. The Modified Stenström otoplasty technique supports the surgeon in the management of underdeveloped antihelix fold, conchal hypertrophy, and obtuse conchoscaphal angle among other deformities. We are the first to evaluate the clinical effects and measure the satisfaction rate post-otoplasty using the modified Stenström technique with a case series study. Methods Six patients were included in the study with a total of 12 ears operated on between February 2021 and July 2022. Utilizing the modified Stenström technique for bilateral protruding ears. All patients had six postoperative follow-up visits with fixed intervals; one week, three weeks, six weeks, three months, six months, and one year. During their one-year postoperative follow-up appointment, all patients completed the satisfaction survey questions. Results Six individuals were studied, three males and three females with a mean age of 23.1 (range, 7-53 years old). There were no complications or recurrences observed. Based on the responses we collected, all patients reported a high satisfaction rate at one-year postoperative follow-up. Conclusion The modified Stenström technique yields good naturally appearing ears. It is an easy and safe technique to apply. It has a short recovery period, and no hospital stay is required. All contribute to a high satisfaction rate among studied patients.

Dementia Knowledge Among Primary Healthcare Physicians in Riyadh, Saudi Arabia.

INTRODUCTION: Dementia poses a significant healthcare challenge globally, and healthcare providers must have adequate knowledge about its diagnosis, management, and support services. By assessing the knowledge level of primary care physicians in Riyadh, we can identify potential gaps and areas for improvement in dementia care, ultimately enhancing patient outcomes and quality of life. This study holds promise in shedding light on the current state of dementia knowledge among primary healthcare physicians in Riyadh and offering insights into strategies to enhance dementia care in this region. METHODS: This cross-sectional questionnaire-based study was conducted from the first of June 2023 to the end of December 2023 in Riyadh, Saudi Arabia. A validated questionnaire was used to assess physicians' knowledge, attitude, and practice toward dementia. RESULTS: A total of 151 physicians completed the questionnaires. The majority were male (55%), below 30 years of age (88.1%), and family medicine residents (84.8%). Most (74.8%) recognized old age as the most significant risk factor; an overwhelming majority of participants (98.7%) could not identify the minimum course of treatment to judge a medication's effectiveness. The average score of correct responses (7.74 ∓ 4.11) was equivalent to 38.7%. Furthermore, the average correct responses were significantly different among the different job levels of the participants. CONCLUSIONS: The findings of this study highlight a lack of knowledge among primary care physicians regarding dementia, emphasizing the crucial importance of physician education in this area. Additionally, the results strongly indicate the need for emphasis on dementia education within the undergraduate medical curriculum, family medicine curriculum, and physician training programs. By addressing these educational gaps, we can better equip physicians to provide optimal care and support for individuals with dementia, ultimately improving patient care and quality of life.

Prevalence of Acute Tonsillitis and Its Association With Oral Hygiene Among the Population of Taif City, Saudi Arabia.

Introduction  Dental surfaces have dense bacterial deposits, and poor oral hygiene can exacerbate bacterial infections, causing acute tonsillitis. The study aims to quantify acute tonsillitis prevalence and assess its association with oral hygiene practices. Methods  A descriptive cross-sectional study aimed to assess the prevalence of acute tonsillitis and its association with oral hygiene was conducted among adults aged 20 and above in Taif City, Saudi Arabia. Illiterates and those unwilling to participate were excluded. We employed an Arabic online self-administered questionnaire that was disseminated conveniently via Google Forms to social media assessing oral hygiene such as last dental visit, age at starting dental care, number of toothbrushes per day, frequency of toothbrush change, and duration of brushing teeth, and acute tonsillitis characteristics of the participants. Results About 393 participated in the study. Of them, 54% were aged 20-30, 53% were males, and 70% had a university education. The prevalence of acute tonsillitis was 64%. Approximately 28% reported dental clinic visits within three months, and 21% initiated oral hygiene practices at age 20. Among participants, 43% brushed twice daily, with 33% spending one minute and 43% two minutes. About 31% replaced toothbrushes every three months, while 23% acknowledged having bad breath. Experiencing bad breath, changing toothbrushes every three months, and having dental visits within less than three months were associated with having acute tonsillitis (p<0.05). However, regression analysis revealed that experiencing bad breath (OR: 2.11, 95% CI: 1.23, 3.70) was associated with a higher risk of acute tonsillitis, while less frequent toothbrush changes correlated with a lower risk (OR: 0.54, 95% CI: 0.30, 0.94). Conclusion  This study revealed a substantial prevalence of acute tonsillitis among adults in Taif City. Oral care practices need improvement. There are significant associations between oral hygiene practices, bad breath, and the occurrence of acute tonsillitis. Addressing oral hygiene practices could be a key focus for preventative measures.

Evaluation of Styloid Process Elongation in Madinah, Saudi Arabia: A Retrospective Radiographic Investigation.

OBJECTIVES: This study aimed to identify the prevalence of an elongated styloid process and analyze the presence of its calcification in the Saudi population using panoramic radiographs. METHODS: The Taibah Outpatient Dental Clinic's OPG radiographs for 962 patients who attended screening clinics between December 2022 and October 2023 were all included in the study. Patients' demographics, such as age, gender, and nationality, as well as radiological data, were included in the following study variables: the presence of an elongated styloid on both sides of a panoramic radiograph, right side styloid length, left side styloid length, right side distal end thickness, and left side distal end thickness. RESULTS: The study evaluated 438 (45.5%) processes found in individuals aged 16-80 years old. The elongated process length ranged from 30.0 to 40.1 mm, and the diameter ranged from 0.81 to 7.79 mm at the origin to 0.56-3.79 mm at the end. There was no statistically significant difference in process length across genders or age groups. The diameters of the styloid bones on the left side vary significantly across genders at the start and completion of the process. CONCLUSION: The prevalence of elongated styloids in the studied population was 4.26%. The radiological evaluation of the styloid process is a crucial stage in dental surgery planning.

The collected data were analyzed using R software version 4.2.2. RESULTS: The majority of the 100 participants were female (76%), and most were over 50 years old (38%). The types of surgery performed included hemithyroidectomy (36%), subtotal thyroidectomy (6%), and total thyroidectomy (58%). Participants reported difficulties related to their senses, body satisfaction, sexual satisfaction, eating, speaking, and social interactions. Pain in the mouth and jaw, as well as swallowing difficulties, showed variations among the surgery groups. Other symptoms, such as tooth problems, dry mouth, and swelling in the neck, did not differ significantly among the groups. Numbness in the hands or feet was associated with a subtotal or total thyroidectomy. Difficulties with enjoying meals, eating in front of others, and communication issues showed variations among the surgery groups. CONCLUSION: This study provided insights into the QOL of thyroidectomy survivors in Taif City. Participants reported challenges related to sensory, body, and sexual issues, as well as difficulties with eating, speaking, and social interactions. The findings highlight the need for interventions and support to address these challenges and optimize the QOL of thyroidectomy patients. Furthermore, research is warranted to explore specific factors contributing to these difficulties and to develop targeted interventions for better patient outcomes.

Knowledge and Attitude Toward Antibiotic Prescription Among Dental Students and Interns at Multiple Universities in Saudi Arabia.

BACKGROUND: Dental students in Saudi Arabia are authorized to write prescriptions for antibiotics during practical training. Adverse side effects and resistance could result from inappropriate prescription. Accordingly, there is a need to evaluate the knowledge of dental students regarding guidelines and applications of antibiotic prescription. OBJECTIVES: To assess the knowledge and attitude toward guidelines and applications of antibiotic prescription among dental students and interns at multiple universities in Saudi Arabia. METHODS: A cross-sectional study was conducted among dental students in their final clinical years (4th to 6th year) and dental interns. The study data were collected using a valid and reliable structured questionnaire comprising three domains: 1) demographic characteristics, 2) knowledge, and 3) attitude toward antibiotic prescription for dental and systemic conditions. The data were analyzed and presented as frequency percentages, and the chi-square test was used to compare the knowledge and attitude items between the dental students and interns. The statistical significance level was set at p ≤ 0.05. RESULTS: A total of 248 participants (women: 55.6%, men: 44.4%) were included in the study. Approximately 21.8% were 4th year students; 17.7%, 5th year students; 12.9%, 6th year students; and 47.6%, interns. For most items, the knowledge level was relatively high, and the attitude was generally positive among the participants. Approximately, 87.1% had good knowledge about current guidelines for antibiotic prophylaxis, 83.9% about antibiotic prescription, and 95.2% about antibiotic resistance. The interns showed significantly higher knowledge levels and favorable attitude, particularly for guidelines and applications of antibiotic prescription and correct use of antibiotics for oral cases, than did the students. Amoxicillin was the most frequently prescribed antibiotic among the participants. CONCLUSION: The interns and 6th-year students demonstrated a relatively high knowledge level and positive attitude toward appropriate antibiotic prescriptions. However, deficiencies were observed among the students in their early clinical years, particularly for systemic conditions. These findings highlight the importance of implementing educational campaigns and providing guidelines to promote the appropriate use of antibiotics among dental students in their final clinical years.

Assessment of Quality and Readability of Web-Based Arabic Knowledge About Cleft Lip and/or Palate: An Infodemiology Study.

OBJECTIVE: The aim of this study is to evaluate the quality and readability of the Arabic web-based information about cleft lip and/or palate (CL/P).Materials and Method: Searching in three engines and checking eligibility for the first 300 websites. The quality of the included websites (72) was assessed using the DISCERN questionnaire, JAMA benchmarks, and HON code. The readability of the websites was assessed using three readability tests: FKGL, SMOG, and FRE. Then, data analysis was done. RESULTS: All checked websites were partly related to CL/P and contained medical facts. The affiliation of most of the websites was commercial 33 (45.8%). The mean overall DISCERN score was 2.87 (± 1.61). The maximum score was not achieved by any website, and only one (1.4%) website had the minimum score. For JAMA benchmarks, the currency was the most achieved item in 39 (54.2%) websites, and none of the websites achieved the four items. Only one website had the HON code. Based on the FRE scale, the level was very easy for most of the websites 57 (79.2%). CONCLUSION: The available content about CL/P is readable but with moderate to poor quality and trustfulness. Undoubtedly, there is a serious need to increase and improve the quality of the web-based Arabic population's knowledge about CL/P, especially by governmental institutions and universities. Establishing specialized websites for CL/P is also needed.

Coexistence of a Nasopalatine Duct Cyst and Radicular Cyst: A Unique Clinical Presentation.

This study discusses a case of coexistence of two distinct cysts, a nasopalatine duct cyst (NPDC) and a radicular cyst, within the anterior region of the maxilla. NPDC is a prevalent non-odontogenic developmental cyst, while radicular cysts are commonly found in odontogenic inflammatory cysts. The clinical and radiographic characteristics of these cysts are explored, emphasizing the importance of accurate diagnosis and treatment planning. In this case, a 51-year-old male patient presented with swelling and pain in the maxillary anterior region. Radiographic examinations revealed a heart-shaped radiolucent lesion extending from tooth 13 to 23, associated with the NPDC, and a separate radicular cyst. Surgical enucleation and tooth extraction were performed as the treatment of choice. This unique case underscores the significance of meticulous radiographic assessment to detect multiple cystic lesions within the same area.

Assessment of Quality and Readability of Online Patient-Centered Arabic Web-Based Knowledge About Apicoectomy.

Background Endodontic microsurgery (apicectomy) can be considered in cases of persistent infection that is resistant to conventional root canal treatment. The aim of this study was to evaluate the quality and readability of the available online information regarding the apicectomy procedure in Arabic. Methods Online search on the three most commonly used websites (Google, Yahoo, and Bing) using one keyword. The first 100 websites from each search were analyzed for quality and readability using DISCERN instrument scores, the Journal of the American Medical Association (JAMA) benchmarks, the Health On the Net (HON) seal, Flesch Reading Ease Scores (FRES), Flesch-Kincaid Grade Level (FKGL), and the Simplified Measure of Gobbledygook (SMOG) Index. Results Searching using the Arabic translation for "root end resection surgery" revealed 349,900 websites. Following the inclusion criteria, 31 websites were selected and evaluated in this study. The selected websites belonged to either non-profit organizations or commercial websites. The quality of most of the selected websites received a moderate score (83.9%) using the DISCERN tool. None of the selected websites obtained the HON seal. Quality evaluation using the JAMA benchmarks revealed that currency was the most achieved item (45.2%), followed by authorship (22.6%). Evaluation of the readability of the selected websites using the FRES, FKGL, and SMOG showed that the included websites were considered readable. Conclusion Although the included websites were readable, the quality of the websites was moderate. There is an urgent need to create more trustworthy and readable websites explaining the different endodontic treatments.

Is Online Patient-Centered Information About Implant Bone Graft Valid?

Background A dental implant is one of the most commonly used treatments to replace missing teeth. A reasonable number of implant cases necessitate using a bone graft before or at the time of implant placement. This study aims to evaluate the quality and readability of online patient-centered information about implant bone grafts. Methodology This cross-sectional study used Google, Yahoo, and Bing search engines. The keywords were entered to screen 900 websites. The DISCERN, Journal of the American Medical Association (JAMA), and Health on the Net (HON) code tools evaluated the included websites for quality. The Flesch reading-ease score (FRES), Flesch-Kincaid grade level, and simple measure of gobbledygook tests measured readability. Statistical analysis was done using SPSS version 25 (IBM Corp., Armonk, NY, USA). Results A total of 161 websites were included; 65 (40.4%) of the included websites belonged to a university or medical center. Only five (3.1%) websites were exclusively related to dental implant treatments. DISCERN showed moderate quality for 82 (50.9%) websites. There was a statistical difference between commercial and non-profit organization websites. In the JAMA evaluation, currency was the most commonly achieved in 67 (41.6%) websites. For the HON code, four (2.5%) websites were certified. Based on FRES, the most common readability category was "fair difficult," accounting for 64 (39.8%), followed by "standard" in 56 (34.8%) websites. Conclusions The study findings suggest that English-language patient-centered information about implant bone grafts is challenging to comprehend and of low quality. Hence, there is a need to establish websites that provide trustworthy, high-quality information on implant bone grafts.

Morpho-Volumetric Changes of the Pharyngeal Airway With Traumatic Maxillofacial Injuries: A Retrospective Radiographic Study.

BACKGROUND: When dealing with traumatized patients, it is crucial to prioritize securing their airway. However, intubating someone who has sustained significant facial injuries can pose difficulties, as the narrow and altered shape of their upper airway may impede their ability to open their mouth. In light of this, the purpose of this study is to evaluate the volumetric and morphological alterations to the upper airway resulting from facial trauma by utilizing computed tomography (CT) scans. METHOD: This is a single-centered retrospective analytical study. This study included CT scans of patients with traumatic facial injuries admitted to King Fahad Hospital in Madinah, Saudi Arabia. Study variables included age, gender, body mass index (BMI), fractured bones, airway symmetry, and airway volume. Using the 3D Slicer software (Slicer Community, USA), a three-dimensional model of the pharyngeal airway was constructed from the CT scan to evaluate symmetry and volume. IBM SPSS Statistics for Windows, version 23 (released 2013; IBM Corp., Armonk, New York, United States) was used to analyze data. RESULTS: Among the screened scans, 136 cases with traumatic facial injuries were included in the study. Age ranged from four to 91 years, with a mean of 28.26 (±14.9). Mandibular and zygomatic fractures were the most common, with 71 (52.2%) and 69 (50.7%) cases, respectively. The pharyngeal airway was symmetric in 111 (81.6%) cases and not symmetric in the other 25 (18.4%) cases. A significant association was found between the side of the fracture and airway asymmetry in mandibular fractures (p-value = 0.03). The total airway volume in the displaced mandibular fractures showed a statistically significant decrease (p-value = 0.019). The fracture sites were not statistically linked to airway asymmetry except for parasymphyseal and symphyseal fractures, with a p-value of 0.038 and 0.041, respectively. CONCLUSION: The study findings suggest that the pharyngeal airway is not usually compromised in most facial bone fractures; however, bilateral displaced mandibular fractures have the potential to diminish the pharyngeal airway volume, especially in fractures involving the symphysis and parasymphysis area.

Parents' Knowledge, Attitude, and Practice Regarding Febrile Convulsion in Children in Riyadh, Saudi Arabia.

Background Fever is a common presentation in pediatric age groups and is the most common reason for healthcare visits. Parents' knowledge is essential for early presentation to healthcare facilities and to prevent possible complications. Studies suggest that febrile convulsions (FCs) often cause stress and anxiety for parents, who often assume it may cause brain damage, future epilepsy attacks, mental retardation, physical injury, and even death. This study aims to assess the knowledge, attitude, and practices of FCs among parents. Methodology This cross-sectional study was conducted among parents living in Riyadh, Saudi Arabia, with children younger than 14 years of age. A self-administered questionnaire was distributed among the selected population using an online survey. The questionnaire included socio-demographic data, family experiences of FC, practice toward a child with FC, and questions assessing knowledge, attitude, and concerns. Results Of the 415 recruited parents, 350 (84.3%) were mothers, and 56.4% were government employees. Regarding monthly income, 172 (41.4%) were earning more than 15,000 SAR per month. The prevalence of parents with having a child with FC was 33%. Overall, 369 (88.9%) had poor knowledge, 41 (9.9%) had moderate knowledge, and only five (1.2%) had good knowledge levels. Regarding attitude, more than one-third (200, 35.2%), had a negative attitude, 205 (49.4%) were neutral, and the rest had positive attitude levels (64, 15.4%). Increased knowledge and attitude toward FC were associated with having a child or siblings of a child with FC. Regarding the practice and the plan of action for future FC occurrence, the most common was to rush the child to a doctor (94, 68.6%), followed by lowering the child's body temperature (78, 56.9%), and placing the child on his/her side (54, 39.4%). Conclusions There was an optimistic attitude toward a child with FC but knowledge was deficient. However, parents who had a child or siblings experiencing FC were more knowledgeable, while parents with higher education and better income tended to exhibit better attitudes when managing a child with FC. Further investigations are needed to establish the level of understanding and perspectives of parents when managing a child with FC.

The Impact of Maxillary Sinus Pneumatization on the Quality of the Alveolar Bone in Dentated and Edentulous Patients: A Cone-Beam Computed Tomography Radiographic Analysis.

Background This study aimed to describe the morphometric differences of maxillary alveolar bone's height, width, and densitometric differences in the posterior region where maxillary sinus pneumatization occurred. Methodology A cross-sectional, cone-beam computed tomography (CBCT) study used 123 CBCT images as a non-randomized convenient sample of sinus pneumatized cases. Bone height, bone width (in mm), and average density of the remaining ridge of all patients were used as study variables. Analysis of the qualitative variables were as frequency and percentages. Parametric Student's t-test and non-parametric chi-squared tests were used to compare the groups. The significance level was set at a p-value ≤0.05. Results The sample included CBCT radiographs for patients who had a mean age of 42.79 ± 12.32 with males constituting 69 (56.1%) of the patients. There was no gender difference between the present and missing teeth at the measured sites of the first premolar, second premolar, first molar, and second molar (p > 0.05). The mean measurements of height and average bone density were significantly higher in the dentate sites; however, the mean width was higher in the edentulous sites (p = 0.001). Conclusions Average bone height and density were significantly decreased at the edentulous sites of sinus pneumatized cases than the dentate sites with no gender difference.

Assessment of Arabic Web-Based Knowledge About Clear Aligners: An Infodemiologic Study.

BACKGROUND: Orthodontic treatments aim to enhance dental aesthetics, functionality, and long-term oral health. Clear aligners have gained popularity as an aesthetic and convenient option for patients seeking orthodontic correction. However, the quality and readability of online Arabic patient-centered information regarding clear aligners has not been studied yet. The aim of our study is to investigate the quality and readability of Arabic patient-centered information about clear aligners. METHODS: We conducted an extensive evaluation of Arabic web-based content pertaining to clear aligners using three prominent search engines. Eligible websites were categorized based on specialization, organizational affiliation, material type, and presentation style. We assessed website quality and reliability using the DISCERN instrument, Journal of American Medical Association (JAMA) benchmarks, and Health on the Net (HON) code. In addition, we measured readability using the Flesch Reading Ease Score (FRES), Simplified Measure of Gobbledygook (SMOG), and Flesch-Kincaid Grade Level (FKGL). RESULTS: Out of 600 search results, 195 websites met the inclusion criteria. None of the websites were HON-code accredited. DISCERN assessments revealed low content quality, with none of the websites achieving high-quality status. The JAMA benchmarks showed limited compliance with the four items, with currency being the most frequently achieved. Readability assessments indicated generally high readability, with FKGL scores suggesting easy comprehension for the average readers. CONCLUSION: While Arabic web-based information on clear aligners is highly readable, its credibility and quality require significant improvement. Websites should adhere to medical information standards, subject content to rigorous assessments, and seek accreditation to ensure reliability. Enhancing the accessibility and comprehensibility of health-related content will empower individuals to make informed health decisions. Addressing limitations, such as social media and video content evaluation, and conducting comparisons with English websites in future research will provide a more comprehensive understanding of the landscape of online orthodontic information.

Assessment of the Relation Between Patterns of Third-Molar Impaction and Blood Group: A Retrospective Study.

Background The prevalence of impacted third molars is high in the global general population. The etiology of impacted third molars is not fully understood, but it is thought to result from combined genetic and environmental factors. Some studies have suggested a link between the blood group and the risk of impacted third molars. This study aimed to investigate the association between the blood group and the presence of impacted third molars and its pattern. Method A total of 856 panoramic radiographs were included in the study. The third molars were evaluated for the pattern of third-molar impaction and blood characteristics recorded as ABO group and presence or absence of Rhesus antigen. Results The results showed no significant association between the blood group and the presence of impacted third molars. The prevalence of at least one impacted the third molar was 34.6%. The most common angulation of impacted third molars was vertical (V) (45.1%), followed by mesioangular (MA) (33.7%), distoangular (DA) (13.8%), and horizontal (H) (7.4%). There was no significant association between the blood group and the number of impacted third molars nor between the blood group and the angulation of the impacted third molars. Conclusion This study suggests that the blood group is not a major factor in the development of impacted third molars. However, further studies with larger sample sizes are needed to confirm these findings.

Prevalence and Characteristics of the Maxillary Sinus Septa in a Saudi Arabian Sub-population: A Retrospective Cone Beam Computed Tomography (CBCT)-Based Study.

OBJECTIVES: This study aims to investigate and determine the prevalence, location, and morphological differences of the maxillary sinus septa using cone beam computed tomography (CBCT) images in the Madina region and to discuss its clinical implications during sinus surgery. METHODS: This study was a retrospective cross-sectional radiographic analysis of 808 CBCT scans from patients who attended Taibah University's College of Dentistry between December 2018 and June 2023. Age, gender, number of septa present per side, location (anterior, middle, posterior), morphology (complete or partial), and type (primary or secondary) were among the study variables. For data statistics, correlation analysis was utilized.  Results: Eight hundred eight CBCT scans were included with a mean age of 34.7±15.08. Septal bone was absent in 60.64% of the sinuses examined. Single septa were more common than multiple septa (p=0.009). Bilateral septal presence and the left septal bone were more common than the right, but none of these distributions were statistically significant. Males showed more sinus septa compared to females, but the difference was not statistically significant (p=0.420). Single septa were more prevalent in people under the age of 25. CONCLUSION: More than 60% of the Madina population had patent sinus cavities with no septal processes, but males with single septal processes predominated.

3D porous polymers for selective removal of CO2 and H2 storage: experimental and computational studies.

In this article, newly designed 3D porous polymers with tuned porosity were synthesized by the polycondensation of tetrakis (4-aminophenyl) methane with pyrrole to form M1 polymer and with phenazine to form M2 polymer. The polymerization reaction used p-formaldehyde as a linker and nitric acid as a catalyst. The newly designed 3D porous polymers showed permanent porosity with a BET surface area of 575 m2/g for M1 and 389 m2/g for M2. The structure and thermal stability were investigated by solid 13C-NMR spectroscopy, Fourier-transform infrared (FT-IR) spectroscopy, and thermogravimetric analysis (TGA). The performance of the synthesized polymers toward CO2 and H2 was evaluated, demonstrating adsorption capacities of 1.85 mmol/g and 2.10 mmol/g for CO2 by M1 and M2, respectively. The importance of the synthesized polymers lies in their selectivity for CO2 capture, with CO2/N2 selectivity of 43 and 51 for M1 and M2, respectively. M1 and M2 polymers showed their capability for hydrogen storage with a capacity of 66 cm3/g (0.6 wt%) and 87 cm3/g (0.8 wt%), respectively, at 1 bar and 77 K. Molecular dynamics (MD) simulations using the grand canonical Monte Carlo (GCMC) method revealed the presence of considerable microporosity on M2, making it highly selective to CO2. The exceptional removal capabilities, combined with the high thermal stability and microporosity, enable M2 to be a potential material for flue gas purification and hydrogen storage.

Knowledge and Awareness Regarding Osteoarthritis and Its Factors in Hail Region, Saudi Arabia.

Objectives Osteoarthritis (OA) is a common chronic degenerative joint disease linked to age, joint overuse abnormalities, and previous trauma. This research aims to assess the awareness levels, as well as the knowledge gap and misconceptions, about OA and its risk factors among the general population in Hail, Saudi Arabia. Methods The research adopted an observational cross-sectional method. Participants from Hail, Saudi Arabia, were recruited and then interviewed between 1 April and 15 July 2022. Adult males and females aged 18 or more were recruited via an online questionnaire using a Google Form link, inviting them to take part in a study concerning their knowledge of OA. The questionnaire was split into three sections. The first section covered demographic data, the second section contained general knowledge regarding OA, and the third section was made up of a 20-item quiz. The collected data was reviewed and then analyzed using the Statistical Package for Social Sciences (SPSS) Version 21 (IBM Corp., Armonk, NY, USA). The statistical methods employed were all two-tailed, with an alpha level of 0.05 considered significant if the P value was less than, or equal to, 0.05. Results Nine hundred six (906) eligible respondents completed the questionnaire. Participants ranged from 18 to 65 in age. More than 66% were female, while 77.5% had a university level of education or above. 13.6% had been diagnosed with OA. Overall, 40.9% of the study participants demonstrated a good knowledge level regarding OA, while 59.1% showed a poor knowledge level. Conclusion The study revealed that the awareness and knowledge levels of the general population in Hail about OA are unsatisfactory. Efforts are recommended to increase the awareness and knowledge of the population through public education, which in turn can lead to a reduction in risk factors and improved early detection of the disease.
